  • FIELD OF THE INVENTION
  • [0004]
    The present invention relates generally to relational databases and, more specifically, to XML data storage, manipulation and queriability.
  • BACKGROUND OF THE INVENTION
  • [0005]
    Extensible Markup Language (XML) is a World Wide Web Consortium (W3C) standard for representing data. Many applications are now being designed to output data in the form of XML documents. Various techniques may be used to store data from such XML documents into a relational database. According to one technique, each XML document is treated as a single data item, and stored as such in a single column of a relational table. This technique is convenient in that the XML does not have to be processed before it is submitted to the database server. However, because the database server considers the XML document a single data item, the database server is unable to take advantage of the fact that XML documents are structured, where a single XML document may include numerous attributes and elements with specific values.
  • [0006]
    According to an alternative technique, an XML document may be split up into its constituent attributes and element data before the XML document is stored in a database. The values for each attribute and element are submitted to the database for insertion in corresponding columns of a table. When this technique is used, the database server may be used to select data based on individual attribute values. However, when the data is retrieved from the database, the attribute values are provided as distinct data items, not as part of a single XML document. To recover the XML document, the data received from the database server must be reformatted and structured to reconstruct the XML document.
  • [0007]
    Based on the foregoing, it is desirable to provide techniques for handling XML documents that do not depend on the specific form in which they are stored. In other words, it is desirable for applications to independently decide on the storage representation of their XML data, and that does not have any impact on the functionality. However, the choice of storage could potentially affect performance of the applications. Further it is also desirable for the database server to implement techniques that exploit the chosen storage representation for optimal processing of user operations.
  • SUMMARY OF THE INVENTION
  • [0008]
    Techniques are provided for modeling XML data using an abstract data type in a relational database system. According to certain embodiments of the invention, the database server stores each XML document in its native form as a single data item within a column, but allows queries to address individual fields within the document. A mechanism is provided to allow the user to store an XML document in a relational database and to submit mapping information that indicates a mapping of each field of the XML document to the column in the relational database in which the data from each field is stored. Regardless of the storage representation, the XML abstract datatype has a set of operations that can be executed by the user. These operations such as extraction and transformation apply to all XML data independent of the storage formats.
  • [0009]
    A mechanism is provided to generate a database query based on an XML query and the mapping information when a user submits the XML query to access the data in the XML document that is stored in the relational database. This process involves rewriting the user queries (and other data manipulation operations) into other queries that better exploit the underlying storage representation of the XML data.
  • [0010]
    Using these techniques, the user need not be aware of the manner in which the XML documents are stored within the database in order to issue queries against the XML documents. The user may simply issue a standard XML query over XML documents, and the database server figures out how to rewrite the query appropriately based on how the XML documents are stored in the database.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • [0015]
    Techniques are provided for modeling XML data using an abstract data type in a relational database system, multiple storage representations, uniform query interface and optimal processing using query rewrites. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.
  • Functional Overview
  • [0016]
    In order to integrate the handling of XML data and SQL data in a relational database, a mechanism is provided to support an XML type datatype in the relational database for storing XML documents within columns and rows of tables. The storage representation may vary from implementation to implementation. The present invention is not limited to any particular storage representation. In certain embodiments of the invention, the user may submit an XML document for storage in the relational database. The data from each field of the XML document is automatically stored in the relational database in a manner that leverages various existing indexing mechanisms associated with storage. For example, when an XML document is submitted for storage in the relational database, a mechanism is provided to determine the corresponding storage column in the relational database for storing each field of the XML document. Thus, each field of the XML document is mapped to some column in the relational database and this mapping information is stored in the relational database. Depending on the type of data, some of the fields of data may be lumped together for storage in a single object relational column while other fields may be stored as separate object relational columns. The data from each field of XML document can be indexed using an appropriate indexing scheme. For example, a B-tree index may be used for columns that contain relational type data and a text index, such as interMedia text, may be used for columns that contain large text data. In certain embodiments, the user may specify the mapping information. By specifying the mapping information, the user may control the granularity of the mapping.
  • [0017]
    Thus, techniques are provided for 1) the uniform handling of XML data and SQL data, 2) a uniform query interface for a well-defined set of XML operations, where the set of operations are decoupled from the underlying storage mechanism for the XML data in the relational database, 3) query rewrites into a form that leverages the data access and data manipulation capabilities of the underlying storage mechanism in the relational database.
  • [0018]
    Uniform Handling of XML Data and SQL Data
  • [0019]
    Typically, in a relational database, there are pre-defined relational data types. Examples of typical pre-defined relational datatypes are number, date, string, etc. Object-relational databases may also contain user-defined object types. However, in order to provide uniform handling of XML data and SQL data, a datatype called XMLType is natively defined in the relational database system. The XMLType datatype can be used for storing any type of XML data, be it structured XML data or unstructured XML data.
  • [0020]
    [0020]FIG. 1 is a block diagram that illustrates the XMLType storage architecture. Block 102 is XML data that is to be stored using the XMLType shown at block 106. The XMLType encapsulates the underlying storage mechanisms for XML data. Some of the storage mechanisms are shown in the storage layer 114. In storage layer 114 is shown a LOB storage mechanism 108, an object relational storage mechanism 110, and an “other” storage mechanism 112. “Other” storage mechanism 112 can be any appropriate storage mechanism for XML data. Thus, the storage mechanisms in storage layer 114 do not comprise the exhaustive set of storage mechanisms for XML data. Because the XMLType encapsulates the underlying storage mechanisms, a user of XML data only sees the XMLType while the actual details of the underlying storage mechanism of the XML data are hidden from the user. Typically, an administrator of the relational database system chooses the underlying storage mechanism for the XML data that is to be stored. The administrator chooses the type of underlying storage mechanism based on performance considerations of the storage mechanism.
  • [0021]
    To illustrate storage, some of the fields of a given XML document may contain structured data. Structured data is data that is capable of being mapped to relational columns in the relational database. In another example, assume that the XML document contains the textual content of an entire book. Rather than exploding such an XML document by mapping every element or field of the XML document to a relational column, only fields that contain data that are likely to be queried by a user are mapped to pre-defined relational types, such as a string, number, etc., while the rest of the data may be lumped together and mapped to one column for Character Large Objects (CLOBs). A user may create his or her own template to specify what fields are to be mapped to relational columns and what fields are to be mapped to CLOBs.
  • [0022]
    [0022]FIG. 2 is a block diagram that illustrates the structure of an XMLType column. Column 204 is an XMLType column that contains an XML document that comprises structured data. The fields of the structured data are mapped into hidden columns 206. For example, the PONO element of the XML document is mapped to a NUMBER column, and PNAME is mapped to a string column. In FIG. 2, the crosshatched area indicates that the columns are hidden from the user's view. The user only sees a single XMLType column.
  • [0023]
    Uniform Query Interface
  • [0024]
    According to certain embodiments of the invention, a uniform query interface is provided in order to define a core set of operations on XMLType data that is stored in the relational database. Such operations are independent of the underlying storage format. According to certain embodiments of the invention, the operations on the XMLType data is functionally abstracted as follows:
  • [0025]
    1) Extract fragments of a given XML document
  • [0026]
    2) Test for existence of certain structures in the XML document
  • [0027]
    3) Extract certain data values in the XML document
  • [0028]
    4) Transforming a given XML document. The above list of operations is not an exhaustive list of operations for XMLType data. To illustrate some of the operations, assume that an XML document called “X” contains purchase order data. The purchase order data includes a purchase order number “PONO” with value “21”, purchase order name “PNAME” with value “JOHN” and a collection of lineitems and appears as follows:
    <PO>
    <PONO>21</PONO>
    <PNAME>JOHN</PNAME>
    <LINEITEM>
    <LINEITEMNO> 100  </LINEITEMNO>
    ....
    </LINEITEM>
    <! Other lineitems>
    </PO>
  • [0029]
    Thus, according to certain embodiments of the invention, an example of the operation for extracting a fragment of XML document “X” is as follows:
  • [0030]
    EXTRACT (X, ‘PO/LINEITEM’)
  • [0031]
    The above operation extracts a fragment of the document X, wherein the fragment is a sub tree comprising of all the branches under LINEITEM.
  • [0032]
    An example of the operation for extracting certain data values in the XML document “X” is as follows:
  • [0033]
    EXTRACTVALUE (X, ‘PO/PNAME’)
  • [0034]
    The above operation extracts the scalar value in PNAME, namely, “JOHN”.
  • [0035]
    An example of the operation for testing for the existence of certain elements in the XML document “X” is as follows:
  • [0036]
    EXISTSNODE (X, ‘PO/[PONO=21]’)
  • [0037]
    The above operation tests whether the XML document “X” has an element called PO, which in turn has a child called PONO whose value is 21.
  • [0038]
    An example of the operation for transforming the XML document using a XSL stylesheet is as follows:
  • [0039]
    TRANSFORM (X, ‘<xsl> . . . stylesheet . . . </xsl>’)
  • [0040]
    The above operations are completely agnostic as to the underlying storage format of the XML document.
  • [0041]
    Query Rewrites
  • [0042]
    According to certain embodiments of the invention, a mechanism is provided for rewriting user queries into a form that leverages the data access and data manipulation capabilities of the underlying storage mechanism in the relational database.
  • [0043]
    The fields of structured data of a given XML document may be mapped into separate relational columns if the data in the fields is likely to be frequently queried by a user. For example, assume that one of the fields of an XML document contains an employee name, and that it is anticipated that users will frequently query the XML documents based on the employee name value. Under these conditions, employee names may be stored in a relational column called ENAME that is separate from the column that stores the XML document itself. If a XML user submits a query to access XML documents based on a particular employee's name, then the XML user's query is automatically rewritten to access only the ENAME column.
  • [0044]
    In contrast, if no query rewrite mechanism is provided and employee names are not stored in a separate column, then, when the XML user submits a query to access a XML documents based on a particular employee's name, a Document Object Model (DOM) is created for each XML document by parsing the XML document. Then the search is performed on the DOM for the employee's name by applying an appropriate XPATH expression. Creating a DOM and then performing a search on the DOM is clearly less efficient.
  • [0045]
    In another example, the existing indexing capabilities of the relational database are used to satisfy the XML user's query. If data is expected to be frequently queried, the data can be stored in a separate relational column, and a B-tree index may be built on that column. Then, if an XML user query is submitted to select, for example, a row where PONO=21, then the B-tree index on the PONO column can be used to identify the rows that contain XML documents that have the value 21 in the PONO column. Similarly, if an XML document is stored as a LOB, then a text index may be used to optimize a search on the LOB column.
  • [0046]
    A mechanism is provided in the database to generate a database query, for example a SQL query, based on the user's XML query and the mapping information associated with the storage of the XML document in the relational database.
  • [0047]
    Referring to FIG. 2, assume that the table of FIG. 2 is called PO-TABLE and that a B-tree index is generated on the relational column PONO. Assume that an XML user submits the following query:
  • [0048]
    SELECT*From PO-TABLE
  • [0049]
    Where EXISTNODE (PO-XML, ‘/PO[PONO=21]’)
  • [0050]
    According to certain embodiments of the invention, the above XML user's query is converted to the following:
  • [0051]
    SELECT*From PO-TABLE
  • [0052]
    Where PO-XML.PONO=21
  • [0053]
    Thus, an index search can be performed for the predicate of PONO.
  • Hardware
  • [0054]
    [0054]FIG. 3 is a block diagram that illustrates a computer system 300 upon which an embodiment of the invention may be implemented. Computer system 300 includes a bus 302 or other communication mechanism for communicating information, and a processor 304 coupled with bus 302 for processing information. Computer system 300 also includes a main memory 306, such as a random access memory (RAM) or other dynamic storage device, coupled to bus 302 for storing information and instructions to be executed by processor 304. Main memory 306 also may be used for storing temporary variables or other intermediate information during execution of instructions to be executed by processor 304. Computer system 300 further includes a read only memory (ROM) 308 or other static storage device coupled to bus 302 for storing static information and instructions for processor 304. A storage device 310, such as a magnetic disk or optical disk, is provided and coupled to bus 302 for storing information and instructions.
  • [0055]
    Computer system 300 may be coupled via bus 302 to a display 312, such as a cathode ray tube (CRT), for displaying information to a computer user. An input device 314, including alphanumeric and other keys, is coupled to bus 302 for communicating information and command selections to processor 304. Another type of user input device is cursor control 316, such as a mouse, a trackball, or cursor direction keys for communicating direction information and command selections to processor 304 and for controlling cursor movement on display 312. This input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allows the device to specify positions in a plane.
  • [0056]
    The invention is related to the use of computer system 300 for implementing the techniques described herein. According to one embodiment of the invention, those techniques are implemented by computer system 300 in response to processor 304 executing one or more sequences of one or more instructions contained in main memory 306. Such instructions may be read into main memory 306 from another computer-readable medium, such as storage device 310. Execution of the sequences of instructions contained in main memory 306 causes processor 304 to perform the process steps described herein. One or more processors in a multi-processing arrangement may also be employed to execute the sequences of instructions contained in main memory 306. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions to implement the invention. Thus, embodiments of the invention are not limited to any specific combination of hardware circuitry and software.
  • [0057]
    The term “computer-readable medium” as used herein refers to any medium that participates in providing instructions to processor 304 for execution. Such a medium may take many forms, including but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media includes, for example, optical or magnetic disks, such as storage device 310. Volatile media includes dynamic memory, such as main memory 306. Transmission media includes coaxial cables, copper wire and fiber optics, including the wires that comprise bus 302. Transmission media can also take the form of acoustic or light waves, such as those generated during radio wave and infrared data communications.
  • [0058]
    Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, or any other magnetic medium, a CD-ROM, any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave as described hereinafter, or any other medium from which a computer can read.
  • [0059]
    Various forms of computer readable media may be involved in carrying one or more sequences of one or more instructions to processor 304 for execution. For example, the instructions may initially be carried on a magnetic disk of a remote computer. The remote computer can load the instructions into its dynamic memory and send the instructions over a telephone line using a modem. A modem local to computer system 300 can receive the data on the telephone line and use an infrared transmitter to convert the data to an infrared signal. An infrared detector coupled to bus 302 can receive the data carried in the infrared signal and place the data on bus 302. Bus 302 carries the data to main memory 306, from which processor 304 retrieves and executes the instructions. The instructions received by main memory 306 may optionally be stored on storage device 310 either before or after execution by processor 304.
  • [0060]
    Computer system 300 also includes a communication interface 318 coupled to bus 302. Communication interface 318 provides a two-way data communication coupling to a network link 320 that is connected to a local network 322. For example, communication interface 318 may be an integrated services digital network (ISDN) card or a modem to provide a data communication connection to a corresponding type of telephone line. As another example, communication interface 318 may be a local area network (LAN) card to provide a data communication connection to a compatible LAN. Wireless links may also be implemented. In any such implementation, communication interface 318 sends and receives electrical, electromagnetic or optical signals that carry digital data streams representing various types of information.
  • [0061]
    Network link 320 typically provides data communication through one or more networks to other data devices. For example, network link 320 may provide a connection through local network 322 to a host computer 324 or to data equipment operated by an Internet Service Provider (ISP) 326. ISP 326 in turn provides data communication services through the worldwide packet data communication network now commonly referred to as the “Internet” 328. Local network 322 and Internet 328 both use electrical, electromagnetic or optical signals that carry digital data streams. The signals through the various networks and the signals on network link 320 and through communication interface 318, which carry the digital data to and from computer system 300, are exemplary forms of carrier waves transporting the information.
  • [0062]
    Computer system 300 can send messages and receive data, including program code, through the network(s), network link 320 and communication interface 318. In the Internet example, a server 330 might transmit a requested code for an application program through Internet 328, ISP 326, local network 322 and communication interface 318. In accordance with the invention, one such downloaded application implements the techniques described herein.
  • [0063]
    The received code may be executed by processor 304 as it is received, and/or stored in storage device 310, or other non-volatile storage for later execution. In this manner, computer system 300 may obtain application code in the form of a carrier wave.
  • [0064]
    In the foregoing specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
